Milk of Magnesia help

Edsst

I have taken milk of magnesia twice after over a week of no bm. I’m drinking tons of water, eating fiber filled fruits, drinking prune juice and have tried colace. NOTHING works except for the MOM. I feel scared taking it since it’s never mentioned as a first option for pregnancy constipation but I am so uncomfortable all the time. If anyone has any input I would really appreciate it. I am 10w 3days.
